Abstract

According to an electric vehicle wireless charging system and method with an automatic reversing positioning function, alternating-current electromagnetic induction type charging is adopted, a charging pile is buried, the charging effective distance is adjusted in the vertical direction when the charging pile is in butt joint with an automobile charging module, the occupied space of a body is saved, accidental damage to the device is avoided, and the service life of the device is prolonged. An automatic positioning parking auxiliary system is introduced in the parking process of the automobilewireless charging parking area, and the safety and convenience of the whole wireless charging process are guaranteed. When the method is implemented, a vehicle firstly drives into the vicinity of a wireless charging area and gets close to the charging pile, the electric vehicle acquires and processes environmental position parameters through a camera and a sensor and then obtains a driving instruction to automatically move to an idle charging pile parking space, the buried charging pile is activated at a specified position, and the charging pile is in butt joint with a vehicle charging moduleto start wireless charging work. According to the invention, the whole process of driving into the charging area, wireless charging, and driving out of the area after charging is intelligent and automatic.

Description

technical field [0001] The invention aims at constructing an intelligent, environment-friendly and convenient wireless charging mode for new energy electric vehicles, and belongs to the technical field of electric vehicle wireless charging. Background technique [0002] Investigations and studies have shown that under today's resource conditions and environmental protection requirements, new energy vehicles, mainly electric vehicles, have gradually entered people's lives, and already have a part of the user base, and the market base is gradually expanding. However, there are still a series of problems in the development of the electric vehicle industry: (1) The number of charging piles is limited, and the space in the city is limited, so it cannot be widely deployed; (2) Most charging piles use wired charging technology, and the charging process is cumbersome. Therefore, wireless charging technology that makes the charging process more convenient is imperative in the field o...
